Description

Technical Field

[0001] The invention relates to the technical field of feed crushing, and in particular to a dust-proof and recycling feed additive energy-saving crushing device. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They are used in small amounts in feed but have significant effects. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products.

[0003] The existing feed additive pulverizing device has the following disadvantages in the production process of feed additives:

[0004] 1. When the raw materials are put into the crushing chamber of the crusher for crushing, the feed additives are prone to generate dust and lack the function of dust absorption and recovery;

[0005] 2. Feed additives are not well refined during crushing. If they are crushed only by crushing blades, the feed additives will inevitably be crushed unevenly, which will affect the crushing effect and quality of the feed additives. Summary of the invention

[0006] The purpose of the present invention is to solve the problems in the background technology and to propose a dust-proof and recycling feed additive energy-saving pulverizing device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A dust-proof and recycling feed additive energy-saving pulverizing device, comprising a pulverizing box and a discharging assembly, wherein the side wall of the pulverizing box is provided with a recycling assembly, and the top of the pulverizing box is fixedly connected to a feeding tank, wherein the feeding tank is provided with a pulverizing assembly, and the top of the feeding tank is provided with a feeding port, wherein a sealing assembly is provided at the feeding port;

[0009] The recovery component includes a suction pipe fixedly connected to the side wall of the crushing box, a coarse filter is provided at the connection between the suction pipe and the crushing box, and an exhaust fan is installed at the end of the suction pipe, a fine filter is fixedly installed in the suction pipe on the side of the exhaust fan close to the crushing box, and a recovery pipe fixedly connected to the bottom of the suction pipe is provided on the side of the fine filter away from the exhaust fan;

[0010] The crushing assembly includes a plurality of crushing shafts vertically rotatably installed in the crushing box, the upper and lower ends of the outer wall of each crushing shaft are connected with coil springs, the two coil springs located at the top are fixed to the inner top wall of the crushing box, the outer wall of each crushing shaft is fixedly installed with a plurality of crushing knives, and the middle section of the outer wall of each crushing shaft is fixedly sleeved with a full gear, and incomplete gears are meshed or separated between the plurality of full gears, a rotating shaft is fixedly installed on the top axis of the incomplete gear, and a driving motor for driving the rotating shaft is fixedly installed on the top of the feeding tank;

[0011] The discharging assembly is placed below the crushing box.

[0012] Preferably, the sealing assembly comprises a sealing plate rotatably mounted on the inner top of the feed tank, two elastic rotating shafts are commonly connected between the end of the sealing plate and the inner top of the feed tank, and the size of the sealing plate is larger than the size of the feed port.

[0013] Preferably, the unloading assembly includes a dual-axis motor fixedly mounted on the side wall of the crushing box, the two output shaft ends of the dual-axis motor are fixedly mounted with drive shafts, and the opposite ends of the two drive shafts are jointly fixedly mounted with a unloading hopper, and the inner wall of the unloading hopper slides in contact with the outer wall of the crushing box.

[0014] Preferably, right-angle fixing frames are fixedly mounted on both the front and rear side walls of the crushing box, and a fixing seat is fixedly mounted on the bottoms of the two right-angle fixing frames.

[0015] Preferably, a filter plate is fixedly installed in the pulverizing box, and the top of the filter plate and the lower end of each pulverizing shaft are rotatably installed, and each of the coil springs and the top of the filter plate located below are fixed.

[0016] Preferably, a spiral feeding plate is fixedly mounted on the outer wall of the rotating shaft, and the outer side of the spiral feeding plate is slidably fitted to the inner surface of the lower port of the feeding tank.

[0017] Compared with the existing technology, the dust-proof recovery feed additive energy-saving pulverizing device provided by the present invention has the following advantages:

[0018] 1. The driving motor controls the rotation of the rotating shaft and the incomplete gear. When the incomplete gear is meshed with the full gear, each crushing knife is driven to rotate through the crushing shaft. At the same time, the coil spring will also undergo elastic deformation. When the incomplete gear is not meshed with the full gear, the crushing shaft will reverse under the action of the coil spring. Thus, under the continuous rotation of the incomplete gear, each crushing shaft and each crushing knife can reciprocate, so that the crushing knife can fully contact the feed additives in the crushing box, thereby improving the crushing effect of the feed additives;

[0019] 2. Start the exhaust fan to draw the dust in the crushing box into the suction pipe. In this process, the coarse filter can intercept the powdered feed additives in the crushing box, and the dust can pass through the coarse filter into the suction pipe. At this time, the dust will be intercepted by the fine filter and fall into the recovery pipe, so as to achieve the effect of dust absorption and recovery in the process of feed additive crushing;

[0020] 3. When the rotating shaft rotates, the spiral feeding plate can be driven to rotate synchronously, so that the feed additives in the feeding tank can be fed into the crushing box at a uniform speed, reducing the crushing difficulty in the crushing box and further improving the crushing effect;

[0021] In summary, the present invention can realize the reciprocating rotation of each crushing shaft and each crushing knife through the intermittent meshing of the incomplete gear and each full gear with the cooperation of the coil spring, so that the crushing knife can fully contact with the feed additive in the crushing box, thereby improving the crushing effect of the feed additive. At the same time, under the action of the exhaust fan, through the cooperation with the coarse filter screen and the fine filter screen, it can also achieve the effect of dust absorption and recovery in the process of feed additive crushing.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figures 1 to 6 A dust-proof and recycling feed additive energy-saving pulverizing device includes a pulverizing box 1 and a discharging assembly. The front and rear side walls of the pulverizing box 1 are fixedly installed with right-angle fixing frames 21, and the bottoms of the two right-angle fixing frames 21 are jointly fixedly installed with a fixing seat 22, which plays a role in supporting and fixing the pulverizing box 1.

[0031] The top of the crushing box 1 is fixedly connected to the feeding tank 2, and a feeding port 3 is opened on the top of the feeding tank 2, and a sealing component is provided at the feeding port 3; the sealing component includes a sealing plate 20 rotatably installed on the top of the feeding tank 2, and two elastic rotating shafts 19 are commonly connected between the end of the sealing plate 20 and the inner top of the feeding tank 2, and the size of the sealing plate 20 is larger than the size of the feeding port 3. When the feed additives are put into the feeding tank 2, the sealing plate 20 is pressed inwardly, or the additives can be piled at the feeding port 3, and under the action of gravity, the sealing plate 20 is rotated inwardly, so that the two elastic rotating shafts 19 are deformed, and the feed additives can enter the feeding tank 2 at this time. After all the feed additives are poured into the feeding tank 2, the sealing plate 20 will be rotated upward and reset under the action of the two elastic rotating shafts 19 to block the feeding port 3, thereby achieving a sealing effect on the feeding tank 2 and ensuring that the dust in the feeding tank 2 will not leak out.

[0032] A recovery component is provided on the side wall of the crushing box 1, and the recovery component includes a suction pipe 4 fixedly connected to the side wall of the crushing box 1, a coarse filter 5 is provided at the connection between the suction pipe 4 and the crushing box 1, and an exhaust fan 6 is installed at the end of the suction pipe 4, and a fine filter 7 fixedly installed in the suction pipe 4 is provided on the side of the exhaust fan 6 close to the crushing box 1, and a recovery pipe 9 fixedly connected to the bottom of the suction pipe 4 is provided on the side of the fine filter 7 away from the exhaust fan 6. When the feed additives in the crushing box 1 are crushed, the exhaust fan 6 is started to draw the dust in the crushing box 1 into the suction pipe 4. In this process, the coarse filter 5 can intercept the powdered feed additives in the crushing box 1, and the dust can pass through the coarse filter 5 into the suction pipe 4. At this time, the dust will be intercepted by the fine filter 7 and fall into the recovery pipe 9, so as to achieve the effect of dust absorption and recovery in the process of feed additive crushing.

[0033] A crushing assembly is provided in the feed tank 2, and the crushing assembly includes a plurality of crushing shafts 11 vertically rotatably installed in the crushing box 1, and the upper and lower ends of the outer wall of each crushing shaft 11 are connected with coil springs 12, and the two coil springs 12 located at the top are fixed to the inner top wall of the crushing box 1, and the outer wall of each crushing shaft 11 is fixedly installed with a plurality of crushing knives 14, and the middle section of the outer wall of each crushing shaft 11 is fixedly sleeved with a full gear 13, and incomplete gears 15 are meshed or separated between the plurality of full gears 13, and a rotating shaft 16 is fixedly installed on the top axis of the incomplete gear 15, and a driving motor for driving the rotating shaft 16 is fixedly installed on the top of the feed tank 2 17, start the driving motor 17 to control the rotation shaft 16 to rotate, so that the incomplete gear 15 rotates. When the incomplete gear 15 is meshed with the full gear 13, each crushing knife 14 will be driven to rotate through the crushing shaft 11. At the same time, the coil spring 12 will also undergo elastic deformation. When the incomplete gear 15 is not meshed with the full gear 13, the crushing shaft 11 will be reversed under the action of the coil spring 12, so that under the continuous rotation of the incomplete gear 15, each crushing shaft 11 and each crushing knife 14 can reciprocate, so that the crushing knife 14 can fully contact with the feed additives in the crushing box 1, thereby improving the crushing effect of the feed additives.

[0034] A filter plate 10 is fixedly installed in the crushing box 1, and the top of the filter plate 10 and the lower end of each crushing shaft 11 are rotatably installed, and each coil spring 12 located below and the top of the filter plate 10 are fixed. During crushing, the filter plate 10 can intercept the feed additives that are not fully crushed, so that they continue to be crushed in the crushing box 1. After being completely crushed, they can pass through the filter plate 10 and fall into the discharge hopper 8.

[0035] A spiral feeding plate 18 is fixedly mounted on the outer wall of the rotating shaft 16, and the outer side of the spiral feeding plate 18 slides in contact with the inner surface of the lower port of the feeding tank 2. When the feed additives are put into the feeding tank 2, the spiral feeding plate 18 can be driven to rotate synchronously when the rotating shaft 16 rotates, so that the feed additives in the feeding tank 2 can be uniformly fed into the crushing box 1, reducing the crushing difficulty in the crushing box 1 and further improving the crushing effect.

[0036] The unloading assembly is placed below the crushing box 1, and the unloading assembly includes a double-axis motor 23 fixedly mounted on the side wall of the crushing box 1. The ends of the two output shafts of the double-axis motor 23 are fixedly mounted with drive shafts 24. The opposite ends of the two drive shafts 24 are jointly fixedly mounted with a unloading hopper 8. The inner wall of the unloading hopper 8 slides and fits the outer wall of the crushing box 1. After the crushing is completed, the double-axis motor 23 is started to control the unloading hopper 8 to rotate clockwise through the two drive shafts 24. When it is tilted, the feed additives inside it can automatically slide down under the action of its own gravity.

[0037] The working principle of the present invention is:

[0038] When in use, the sealing plate 20 is pressed inward, or the additives can be piled at the feeding port 3. Under the action of gravity, the sealing plate 20 is rotated inward, so that the two elastic shafts 19 are deformed, and the feed additives can enter the feeding tank 2. After all the feed additives are poured into the feeding tank 2, the sealing plate 20 will be rotated upward and reset under the action of the two elastic shafts 19 to cover the feeding port 3, thereby achieving a sealing effect on the feeding tank 2.

[0039] The driving motor 17 is started to control the rotation of the rotating shaft 16, and the spiral feeding plate 18 is driven to rotate synchronously, so that the feed additive in the feeding tank 2 can be fed into the crushing box 1 at a uniform speed, reducing the crushing difficulty in the crushing box 1;

[0040] When the rotating shaft 16 rotates, it can also drive the incomplete gear 15 to rotate. When the incomplete gear 15 is meshed with the full gear 13, each pulverizing knife 14 will be driven to rotate through the pulverizing shaft 11. At the same time, the coil spring 12 will also undergo elastic deformation. When the incomplete gear 15 is not meshed with the full gear 13, the pulverizing shaft 11 will reverse under the action of the coil spring 12. Therefore, under the continuous rotation of the incomplete gear 15, each pulverizing shaft 11 and each pulverizing knife 14 can achieve reciprocating rotation, so that the pulverizing knife 14 can fully contact the feed additive in the pulverizing box 1.

[0041] At the same time, the exhaust fan 6 is started to draw the dust in the crushing box 1 into the suction pipe 4. In this process, the coarse filter 5 can intercept the powdered feed additive in the crushing box 1, and the dust can pass through the coarse filter 5 into the suction pipe 4. At this time, the dust will be intercepted by the fine filter 7 and fall into the recovery pipe 9, so that the effect of dust absorption and recovery can be achieved in the process of crushing the feed additive.

[0042] Finally, after the crushing is completed, the dual-axis motor 23 is started to control the discharge hopper 8 to rotate clockwise through the two drive shafts 24. When the discharge hopper 8 is tilted, the feed additive inside the discharge hopper 8 can automatically slide downward under the action of its own gravity.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
